trouble using ocrFile()

[ageyl]

I'm attempting to use the ocrFile() function to read pdf image of a table. If I use Abbyyr's "finreaderonline.com" with my pdfs I get a nice .csv table back.

When I use ocrFile() I get the following error message:
Error in Ops.factor(res$id, listFinishedTasks()$id) : level sets of factors are different

If I run getAppInfo()
getAppInfo() Name of Application: 1 No. of Pages Remaining: 1 No. of Fields Remaining: 1 Application Credits Expire on: 1 Type: 1

Any ideas about what I could check?

Interesting. Let me investigate.

Apologies for the long delay. I believe the error you are getting is caused by the presence of factors instead of character vector. I have coerced to char as a fix.
Ping me if the latest version of abbyyR still gives you problems.
